Primare I35 Modular Integrated Amplifier at Vinyl Sound Buffalo, NY USA

The I35 is a modular full-size integrated amplifier from Primare (Malmö, Sweden), available at Vinyl Sound in Buffalo, NY, USA. Built on Primare's UFPD 2 all-analog Class-D amplification platform, it delivers 150W per channel into 8Ω and 300W into 4Ω with absolute linearity across the entire audible bandwidth — making it the most powerful integrated amplifier in Primare's modular range. Featuring 2 × balanced XLR inputs and 3 × RCA analog inputs, and designed to accept the optional DM35 DAC module and SM35 Prisma streaming module at any time, the I35 is Primare's most future-proof and expandable integrated amplifier platform.

UFPD 2 Amplification — Performance Without Compromise

UFPD 2 (Ultra Fast Power Device 2) is Primare's proprietary all-analog Class-D technology — a fundamental reworking of its predecessor UFPD that delivers linear amplification across the full audible bandwidth without the thermal trade-offs of Class AB design. The I35 provides 150W into 8Ω and 300W into 4Ω with vanishingly low distortion and an ultra-wide frequency response. The signature sound character is fast, controlled, and precise — with the kind of grip on low frequencies and articulation through the midrange that high-power Class D, done correctly, uniquely provides. The balanced XLR inputs allow the I35 to be connected to any balanced preamplifier, DAC, or streaming source for full differential signal transmission.

Modular Design — Built for Now and the Future

The I35's modular architecture is a cornerstone of the Primare ecosystem. At purchase, the I35 operates as a pure analog integrated amplifier with five inputs (two XLR, three RCA). At any later point, the optional DM35 DAC module can be added for high-resolution digital conversion, and the SM35 Prisma network streaming module can be installed to bring AirPlay 2, Chromecast, Spotify Connect, and Roon Ready capability without replacing the amplifier. This means the I35 can grow with a system over time, from a pure analog integrated to a fully streaming, multi-room capable hub, entirely within the original chassis. It pairs naturally with Primare's DD35 CD transport, CD35 Prisma CD player, and PRE35 preamplifier.

Frequently Asked Questions

What is the Primare I35?

The Primare I35 is a modular full-size integrated amplifier from Primare (Sweden) using UFPD 2 all-analog Class-D amplification to deliver 150W per channel into 8Ω and 300W into 4Ω. It includes two balanced XLR input pairs and three RCA inputs, and accepts the optional DM35 DAC and SM35 Prisma streaming modules at any time — making it Primare's most powerful and flexible integrated amplifier platform. It is available at Vinyl Sound in Buffalo, NY, USA.

How does the Primare I35 compare to the Primare I25?

The I35 and I25 share the same UFPD 2 amplification technology and modular upgrade path, but differ in power output and input configuration. The I35 delivers 150W per channel into 8Ω versus 100W for the I25, and 300W versus 200W into 4Ω. The I35 also adds two balanced XLR input pairs, whereas the I25 provides only RCA inputs. For larger rooms, more demanding loudspeakers, or systems requiring balanced preamplifier connectivity, the I35 is the preferred choice.

How does the Primare I35 compare to the Hegel H190?

The Primare I35 and Hegel H190 are both premium 150W integrated amplifiers from Scandinavian manufacturers. The H190 uses Hegel's Class AB SoundEngine 2 topology and includes a built-in DAC and network streaming. The I35 uses Primare's UFPD 2 all-analog Class-D technology and is offered in a modular form: start with a pure analog integrated, then add the DM35 DAC and SM35 Prisma modules when needed. The Primare approach lets buyers invest in the amplifier first without paying for digital features they may not require immediately. The I35 also provides a higher-specification streaming platform via Prisma once that module is added, including Chromecast built-in and AirPlay 2.

Can I add a DAC and streaming to the Primare I35 after purchase?

Yes. The I35 accepts the optional DM35 DAC module and the SM35 Prisma network streaming module, either at purchase or at any later date. The DM35 adds high-resolution digital conversion and USB input capability. The SM35 Prisma adds AirPlay 2, Chromecast built-in, Bluetooth, Spotify Connect, and Roon Ready streaming with multi-room control. Both modules are installed internally and do not require replacement of the amplifier chassis.

What loudspeakers pair well with the Primare I35?

The I35's 150W per channel into 8Ω and 300W into 4Ω output, combined with the low-distortion character of UFPD 2 amplification, makes it well suited to a wide range of loudspeakers. It handles low-impedance loads and high-sensitivity designs with equal composure. Particularly strong pairings include Primare-recommended brands available at Vinyl Sound Buffalo — such as Focal, DALI, Dynaudio, Klipsch, Wharfedale, and Totem Acoustic — across floorstanding, standmount, and demanding audiophile designs.
